indicator lamp located in the
center console will be illuminated, except
with the key removed or in the steering
lock position0.Self-test BabySmart
TM
without special
child seat installed
After turning the key in the steering lock to
position1 or2, the
7
indicator lamp
located in the center console lights up for
approx. 6 seconds and then goes out.
If the indicator lamp should not come on or
is continuously lit, the system is not func-
tioning. You must see an authorized
Mercedes-Benz Center before seating any
child on the passenger seat.
More information can be found in the
“Practical hints” section (page 205).
iThe system does not deactivate the
side impact airbag and the emergency
tensioning device.
Warning!
G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
